Explain briefly about longitudinal wave & Transverse wave?
|Longitudinal Wave||Transverse Wave|
|Longitudinal waves are those in which the particles of the medium oscillates parallel to the propagation of the wave.||Transverse waves are those in which the particles of the medium oscillates perpendicular to the direction of the wave.|
|Longitudinal wave always needs a medium to propagate. These are mechanical waves. Wave propagating along the length of a spring is a longitudinal wave. Sound wave is a longitudinal wave.||Transverse wave that needs medium to propagate is a mechanical wave. Water waves (formation of ripples in a pond) are transverse waves. Electromagnetic waves (example: light) are also transverse waves (electric and magnetic field oscillates perpendicular to the propagation of the wave) but these waves don't need a medium to propagate.|
Longitudnal- these are waves in particles of mediam viberate to and fro (forward and backwards) in the direction of propagation. Ex. Sound waves Transverse- these are waves in particles of mediam viberate in a perpendicular direction of the propagation of wave. Ex. Light waves
